I bought a house and the previous owner had an ADT Safewatch Pro 3000 installed. I think the board is dead because four resistors above terminals 1 and 2 are burned and partially melted. The original 1361X10N transformer also doesn’t seem to put out any AC voltage, so I assume that’s dead too.
I ordered a new VISTA-20P and plan to rewire everything to the new board. The new transformer has only two load terminals, while the 1361X10N had two load terminals plus ‘Sync Output,’ ‘Signal Common,’ and ‘X10 Data’ terminals. The black, red, and green wires from these terminals go to an 8-pin connector on the board, but the other wires are cut and don’t seem to do anything.
A few questions:
What’s the best way to move forward?
I know replacing the board means new programming. Any advice for that?
What exactly does the X10 transformer/8-pin connection do?
I have an ADT-branded 6272 keypad with their logo all over it. Will this still work with the new board?
It says: ‘USE 4300 / 1321X10 TRANSFORMER INTERFACE IN PLACE OF 1321 OR 1321CN WHEN POWER LINE CARRIER DEVICES ARE BEING USED. (SEE INSTRUCTIONS FOR CONNECTIONS)’
If you’re not using that feature, just wire the power to the two terminals on the panel and ignore the 8-pin connector. If you want to use the feature, you’ll need to get the other transformer.
Your 6272 keypad should still work with the VISTA-20P. The VISTA-20P is the actual panel, not the keypad.
If the board is fried, replacing it is your best bet. Just be sure to document how everything is currently wired before disconnecting anything. Take pictures if needed so you can reference them later.
Programming a new panel can be time-consuming, but if you’re comfortable with it, start with the installer manual. Honeywell panels use a series of data entry codes for programming, so be patient and go step by step.
Since your transformer is dead too, check your wiring for any shorts before powering up the new board. A short could have caused the failure in the first place.
